Watch the Talkative Dude online guitar lesson by Andrew Ford from 30 Rock Bass Grooves for Beginners You MUST Know

Groove 15 is a country flavored groove inspired by "Ramblin' Man" by the Allman Brothers. One of the things I love about the basslines from the 70's era in rock is that they were inspired by a variety of styles of music. This is a 4-bar phrase in the key of Ab. Again, a different use of our dotted quarter rhythm. Our counting on this groove moves fast because of the tempo, so practice slow and work up to tempo. The first bar is the chord Ab and starts on the root with the dotted quarter and moves to C playing the eighth note, we hold that C and follow it with an Eb. That combination of 3 notes is called a triad. We end that bar with F playing on beat 4.

The next bar has two chords (Gb to Db), starting with the Gb chord, but instead of playing the root, we play the 5 (Db) with a half note rhythm, a melodic twist, and then on beats 3 and 4 over the Db chord we play the root Db and Eb. In Bar 3, we return to the exact pattern from Bar 1, but this time it hangs on the Ab chord, allowing us to play a nice quarter note pattern using the root's octave (Ab) on the D string for two beats and then a common pattern using the 6 (F) and the 5 (Eb) to bring us back around to the Ab. This is another major pentatonic style pattern using the 1, 3, 5, and 6 of the chord Ab.
